This sounds like a more advanced use-case that would require more hooks into ML at the Stratimikos level and is very ML-specific. Could you use to Stratimikos::DefaultLinearSolver builder objects and some of your own wrapper code to construct this? Does ML already have built-in support to use AztecOO internally? This might be more of question for the ML developers.
